Spidigo — customer service is terrible.

I have invested around 5k for the broadband service but the internet service remains shut majorly. On top of this they do not provide customer support.
Their customer support number do not work. We feel helpless and money is wasted.
I am fed up of calling them and taking follow up every day.
Since last 3 days they not responding to any calls or messages.
I want my refund now and want to discontinue their service as it has direct impact on my work.
